IMPROVEMENT IN TRUCKS FOR MOVING BUILDINGS.

Specification forming part of Letters Patent No. 134,950, dated January14, 1873.

To all whom it may concern:

Be it known that I, WILLIAM E. JVVALKER, of Albion, in the county ofMarshall and State of Iowa, have invented a new and useful Improvementin Trucks for Moving Buildings, of which the following is aspecification:

This invention relates to a truck for facilitating the operation ofmoving buildings; and consists in the construction and arrangement ofparts hereinafter described.

In the accompanying drawing, Figure 1 rep resents a longitudinalvertical section of the truck, taken on the line a m of Fig. 2. Fig. 2is a top or plan view.

Similar letters of reference indicate corresponding parts.

A A represent two broad truck-wheels on the axle B, with a space betweenthem, which admits the sandboa-rd (J. This sand board rises up to thesurface of the wheels, and the broad bolster D rests thereon. E is thekingbolt, which passes down through the bolster, sand-board, and axle,as seen in Fig. 1. F is the bolster-plate. The'upper end of the kingboltprojects above the bolster and plate, and is a little tapering, and isintended to enter the under side of the sill of the building to bemoved. G G represent the regulating-arms, attached to each end of thebolster, to which they are firmly secured by the iron straps H. Irepresents a stay-brace, attached to the under side of the bolster,which passes through the sand-board. J is a brace, of similar shape,with its ends attached to the under side of the bolster, which passesdown and under the axle, where it receives the lower end of theking-bolt, as seen in Fig. 1. These braces are so attached and connectedwith the axle and sand-board that the bolster may be turned to the rightor left, as may be desired, to vary the direction of the building. Krepresents holes in the bolster, by means of which the bolster may beattached to the sill of the building by screws. The truck will run on atrack laid for the purpose of planks or timber. L L are chains, attachedto the ends of the axle, or to the linch-pins and to theregulating-arms, as seen in Fig. 2, when the line of motion is straight.When it is necessary to turn in either direction one of the chains islet out and the other one is taken up, so that the bolster is heldstationary into any desired position.

Four, more or less, of these trucks are placed under the building to bemoved. They simply sustain the weight and facilitate the movement of thebuilding, the motive power being applied independently thereof.

Having thus described my invention, I claim as new and desire to secureby Letters Patent- The braces IJ, when combined and arranged, asdescribed, with the axle B, sand-board (J having curved slot, bolster D,and king-bolt E, so that the bolster is thus reenforced and strengthenedwithout being prevented from turning in the sand-board.
